Abstract

Systems and methodologies are described that facilitate scheduling via a power control algorithm that dynamically update a scheduling metric (e.g., adjusting transmission power for sub-carriers) based on a prediction function and/or inference model of expected power requirements. In one aspect, the power prediction component can include two further components, namely: the data channel component and the control channel component-wherein a carrier to interference ratio (C/I) information is being transmitted on such control channel and the power is adjusted to obtain performance requirements. Accordingly, an efficient scheduling of users on a reverse link in an orthogonal manner can be provided, to optimally use system resources, while simultaneously: maintaining a predetermined and/or arbitrary fairness metrics, maintaining quality of service and maximizing throughput.
